If you want to say the reason, I think it's actually the wine. Ancient literati and generals all loved to drink. Before writing poetry, people had to drink to make wine, and military commanders had to drink to fight. Even after Song Wu beat Jiang Menshen, the tiger was drunk. However, they didn't expect that drinking would be a mistake.
Cao Zhi was clever since childhood and was the third son of Cao Cao. At an early age, he showed his intelligence and quick thinking. No father dislikes his son's cleverness. Some people say that Cao Cao is actually afraid of Cao Zhi, but it is actually nonsense. If Cao Cao wanted to be an emperor, he would have done it long ago, and everything he did later was for his descendants. Therefore, Cao Zhi is the most appreciated and loved among Cao Cao's philosophers, and even tried to make Cao Zhi his successor several times.
However, because of the wine, he repeatedly made big mistakes and was finally rejected by Cao Cao. For the first time, Cao Zhi didn't know why he was drunk, so he drove the carriage to Sima Gate and opened Sima Gate to travel from it. You know, only the emperor can cross Sima Gate, even the prince can't. However, Cao Cao, who still has feelings for the Han Dynasty, also ordered not to open Sima Gate privately. Cao Zhi violated a political bottom line this time.
Cao Cao was so angry that he directly gave three orders to criticize Cao Zhi, knowing that this has never happened before. But also directly let Cao Pi-li be the successor. But how can a child who has loved since childhood say give up so easily? So in the critical period when General Coss was besieged by Guan Yu, Cao Cao ordered Cao Zhi to lead the troops to rescue him.
After all, Cao Cao has great potential. As long as there are military forces passing by, there is basically no problem in solving difficulties. It can be seen from here that Cao Cao's purpose is to make Cao Zhi achieve military achievements. But I never imagined that this may be the reason why Cao Zhi's psychology is too fragile. After being criticized, he drank day and night, and even was ordered to drink before leaving his job. I ended up unconscious when I left.
How can Cao hold himself back? On the one hand, forbearance is mainly because Cao saw his own shortcomings and thought that he could do nothing psychologically. So he gave up and began to fully support xelloss. However, Cao Cao's support for Cao Zhi was still very strong, so Cao Cao helped Cao Pi cut Cao Zhi's wings.
Cao Zhi was even more disorganized. He kept drinking every day, stopped taking care of things, and eventually died of depression. Therefore, all his tragedies stem from wine, and I hope everyone will take a warning. Although drinking is beautiful, don't drink too much.
